It is not possible to die that quickly from this happening... It could be possible if left untreated for days, etc.

What most likely happened was sudden drop in blood pressure due to shock, Adrenaline from the event could have also sped up his heart rate and caused him to have a myocardial infarction, His blood pressure could have sky rocketed as well causing this same event, Heck he could have choked on his own tongue due to the shock...
